[0031] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0032] In the description of the embodiments of the present utility model, for the convenience of explanation, as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown by the arrow in the figure, the direction of the arrow X is the "length direction of the shell"; Figure 1 and Figure 5 As shown by the arrow in , the direction of arrow Y is the "width direction of the shell". Figure 1 and Figure 2As shown by the arrow in , the direction of arrow Z is the "height direction of the housing". It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present application.

[0033] The present invention provides an aerosol generating device. Figure 1 , Figure 5 and Figure 7 The aerosol generating device includes a shell 10 and an antenna panel 20.

[0034] An installation cavity 10a is provided inside the housing 10. The installation cavity 10a is used to place and install other components in the aerosol generating device to play a protective role.

[0035] It can be understood that the outer surface of the shell 10 forms at least a part of the outer contour surface of the aerosol generating device so as to be directly exposed to the outside.

[0036] The antenna panel 20 is used to send and receive electromagnetic wave signals. In other words, data information in the aerosol generating device is sent through the antenna panel 20, or external command information is received through the antenna panel 20.

[0037] It can be understood that the antenna panel 20 is a flat-plate antenna, and the area for transmitting and receiving electromagnetic waves is a plane.

[0038] The antenna panel 20 is located in the installation cavity 10 a , so that the housing 10 can protect the antenna panel 20 to a certain extent.

[0039] It should be noted that the specific distance and related structures of the antenna panel 20 for transmitting and receiving electromagnetic wave signals have been applied in the relevant technology and will not be elaborated here.

[0040] A portion of the outer surface of the housing 10 forms an indication surface 10b, which is a plane and forms a portion of the outer contour surface of the aerosol generating device, that is, the indication surface 10b is directly exposed to the outside of the aerosol generating device.

[0041] The antenna panel 20 is located on the back side of the indicating surface 10b, which means that on the projection plane perpendicular to the normal direction of the indicating surface 10b, the projection of the antenna panel 20 and the projection of the indicating surface 10b at least partially overlap, so that the antenna panel 20 is as close to the indicating surface 10b as possible.

[0042] The radiation direction of the antenna panel 20 is toward the indication surface 10 b and is the same as the normal direction of the indication surface 10 b.

[0043] The radiation direction of the antenna panel 20 refers to the direction of the main lobe of the antenna panel 20 , that is, the direction of the maximum radiation beam in the electromagnetic wave beam emitted by the antenna panel 20 .

[0044] That is, the area of ​​the antenna panel 20 receiving and transmitting electromagnetic waves is parallel to the indication surface 10b, so that the average distance from the outer contour surface of the aerosol generating device where the indication surface 10b is located to the area of ​​the antenna panel 20 receiving and transmitting electromagnetic waves is equal.

[0045] At least part of the other surfaces of the outer surface of the shell 10 connected to the indicating surface 10b is a curved surface; or, at least part of the other planes of the outer surface of the shell 10 adjacent to the indicating surface 10b is inclined relative to the indicating surface 10b.

[0046] The other surfaces of the outer surface of the housing 10 connected to the indication surface 10b refer to the surfaces connected to the boundary of the indication surface 10b among the multiple surfaces forming the outer surface of the housing 10. At least part of these surfaces are arc surfaces.

[0047] The indication surface 10 b is a plane. Compared with the curved surface connected to the indication surface 10 b , the indication surface 10 b is more adaptable to the plate-like structure of the antenna panel 20 , thereby facilitating increasing the area of ​​the antenna panel 20 .

[0048] Some planes in the outer surface of the housing 10 adjacent to the indicating surface 10 b are inclined relative to the indicating surface 10 b , that is, the outer surface of the housing 10 has a plurality of planes, a part of which forms the indicating surface 10 b .

[0049] The plane adjacent to the indicating surface 10b may be a plane directly connected to the boundary of the plane where the indicating surface 10b is located; or it may be a plane spaced from the boundary of the plane where the indicating surface 10b is located, and one or more arc surfaces are arranged between the plane and the indicating surface 10b.

[0050] The indicating surface 10 b is tilted with respect to the plane adjacent thereto, which means that the two planes are neither perpendicular nor coplanar, which is beneficial to increasing the area of ​​the indicating surface 10 b and further to increasing the area of ​​the antenna panel 20 .

[0051] The aerosol generating device in the embodiment of the utility model forms a planar indicating surface 10b on the surface of the shell 10, which, on the one hand, is conducive to increasing the area of ​​the antenna panel 20, thereby improving the signal receiving and transmitting efficiency of the antenna panel 20; on the other hand, the indicating surface 10b is in a planar form on the outer contour surface of the aerosol generating device, which is convenient for the user to directly identify the position of the indicating surface 10b on the aerosol generating device. The user can point the indicating surface 10b toward the device that needs to communicate with the aerosol generating device, so as to improve the accuracy of data information transmission and reception and enhance the user experience.

[0052] The specific shape of the indication surface 10b is not limited, such as circular, polygonal, etc.

[0053] The shape of the indication surface 10 b may be the same as or different from the shape of the region of the antenna panel 20 that transmits and receives electromagnetic waves.

[0054] The indication surface 10 b may be one of a plurality of planes on the outer surface of the housing 10 , or may be the only plane on the outer surface of the housing 10 .

[0055] For example, see Figure 7 In a cross section of the shell 10 perpendicular to its length direction, a portion of the outer boundary of the cross section is an arc line, and the other portion is a straight line formed by the indicating surface 10b. That is to say, a portion of the outer surface of the shell 10 is an arc surface, and a portion is an indicating surface 10b. In this way, while it is convenient for the user to hold the shell 10, an indicating surface 10b with an obvious indicating function is formed on the surface of the shell 10, so that the user can rotate the shell 10 to an appropriate position so that the indicating surface 10b faces the device that needs to communicate with the aerosol generating device.

[0056] In some embodiments, see Figure 2 and Figure 3 On a projection plane perpendicular to the normal direction of the indication surface 10 b , the projection of the indication surface 10 b is at least partially located within the projection range of the antenna panel 20 .

[0057] That is, the projection of the indication surface 10 b at least partially overlaps with the projection of the antenna panel 20 .

[0058] This is beneficial to further increase the area of ​​the antenna panel 20, thereby further beneficial to reduce the energy loss of electromagnetic waves and reduce the adverse effect of the shell 10 on the antenna panel 20 receiving and transmitting electromagnetic waves.

[0059] The specific material of the housing 10 is not limited, such as plastic, metal, etc.

[0060] It can be understood that in the embodiment where the shell 10 is made of metal, since the shell 10 encloses the installation cavity 10a, the shell 10 forms a Faraday cage to produce electrostatic shielding, thereby severely weakening or even blocking the antenna panel 20 in the installation cavity 10a from receiving and transmitting electromagnetic wave signals.

[0061] In some embodiments, see Figures 1 to 3 as well as Figure 7 The indication surface 10b is provided with a through hole 10c, and the through hole 10c penetrates the shell 10 along the normal direction of the indication surface 10b. On the projection plane perpendicular to the normal direction of the indication surface 10b, the projection of the antenna panel 20 is located within the projection range of the through hole 10c.

[0062] That is, the electromagnetic waves emitted by the antenna panel 20 can directly pass through the through hole 10 c to the outside of the aerosol generating device, or the external electromagnetic waves can directly pass through the through hole 10 c into the installation cavity 10 a and be received by the antenna panel 20 .

[0063] In this way, the shielding effect of the shell 10 on electromagnetic waves is further reduced, and the adverse effect of the shell 10 on the antenna panel 20 receiving and transmitting electromagnetic waves is reduced.

[0064] It is understandable that the antenna panel 20 does not extend into the through hole 10c, so that the edge of the opening of the through hole 10c located on the outer surface of the shell 10 plays a shielding role, thereby reducing the probability of external foreign matter extending into the through hole 10c and damaging the antenna panel 20.

[0065] It can be understood that, on the projection plane perpendicular to the normal direction of the indication surface 10b, the shape of the projection of the through hole 10c and the shape of the area of ​​the antenna panel 20 for transmitting and receiving electromagnetic waves may be the same as or different from each other.

[0066] In some embodiments, on a projection plane perpendicular to the normal direction of the indicating surface 10b, a projection range of the opening of the through hole 10c on the outer surface of the shell 10 is larger than a projection range of the opening of the through hole 10c on the inner wall of the mounting cavity 10a, so as to further reduce the shielding effect of the shell 10 on electromagnetic waves.

[0067] It is understandable that by increasing the area of ​​the antenna panel 20 for transmitting and receiving electromagnetic waves, the effect of the antenna panel 20 for transmitting and receiving electromagnetic waves can also be improved.

[0068] In some embodiments, see Figure 1 and 5 Among the length direction, width direction and height direction of the housing 10, the normal direction of the indication surface 10b is inclined to two of them, and the remaining one is perpendicular to the normal direction of the indication surface 10b.

[0069] That is to say, the normal direction of the indicating surface 10b is greater than 0° and less than 90° with respect to two of the linear directions of the length direction, width direction and height direction of the shell 10, and the indicating surface 10b is parallel to the remaining one.

[0070] The length direction of the housing 10 refers to the straight line direction where the largest of the three-dimensional dimensions of the housing 10 is located.

[0071] The width direction of the housing 10 and the height direction of the housing 10 refer to two directions that are orthogonal to the length direction of the housing 10 , and the two directions are orthogonal to each other.

[0072] For example, see Figure 1The normal direction of the indication surface 10b is inclined to the length direction of the shell 10 and the height direction of the shell 10, while the width direction of the shell 10 is perpendicular to the normal direction of the indication surface 10b.

[0073] For example, see Figure 5 The normal direction of the indication surface 10b is inclined to the width direction of the shell 10 and the height direction of the shell 10, while the length direction of the shell 10 is perpendicular to the normal direction of the indication surface 10b.

[0074] This is beneficial for increasing the area of ​​the antenna panel 20 for receiving and transmitting electromagnetic waves as much as possible while keeping the dimensions of the shell 10 in the length, width and height directions constant, thereby improving the effect of the antenna panel 20 for receiving and transmitting electromagnetic waves.

[0075] In some embodiments, see Figure 5 , the normal direction of the indication surface 10 b is perpendicular to the length direction of the outer contour of the housing 10 . In other words, the indication surface 10 b is parallel to the length direction of the housing 10 .

[0076] Since the length direction of the shell 10 is the direction of the largest dimension among the three-dimensional dimensions of the shell 10, the indicating surface 10b extends along this direction and is inclined to the width direction and the height direction of the shell 10, which is conducive to more fully utilizing the space of the installation cavity 10a along the length direction of the shell 10, and further increasing the area of ​​the region where the antenna panel 20 receives and transmits electromagnetic waves.

[0077] It can be understood that the inner wall of the installation cavity 10 a constrains the arrangement of the antenna panel 20 .

[0078] In some embodiments, see Figure 6 A portion of the inner wall of the installation cavity 10a forms an avoidance surface 10d, the avoidance surface 10d is located on the back side of the indication surface 10b, the avoidance surface 10d is a plane, and the normal direction of the avoidance surface 10d is parallel to the normal direction of the indication surface 10b.

[0079] The extension direction of the avoidance surface 10d is adapted to the extension direction of the area of ​​the antenna panel 20 that receives and transmits electromagnetic waves, so that the two are arranged in parallel, which is conducive to reducing the distance between the two. In this way, it is conducive to reducing the distance between the area of ​​the antenna panel 20 that receives and transmits electromagnetic waves and the inner wall of the installation cavity 10a, thereby reducing the distance between the area of ​​the antenna panel 20 that receives and transmits electromagnetic waves and the indication surface 10b, so as to improve the effect of the antenna receiving and transmitting electromagnetic waves.

[0080] In some embodiments, on a projection surface perpendicular to the normal direction of the indication surface 10b, the projection of the avoidance surface 10d is located within the projection range of the indication surface 10b.

[0081] This helps to further reduce the distance between the area where the antenna panel 20 receives and transmits electromagnetic waves and the indication surface 10 b.

[0082] The avoidance surface 10d and the antenna panel 20 may be spaced apart from each other, or they may be in contact with each other.

[0083] The shape of the avoidance surface 10d may be the same as or different from the shape of the region of the antenna panel 20 that transmits and receives electromagnetic waves.

[0084] The shape of the avoidance surface 10d may be the same as or different from the shape of the indication surface 10b.

[0085] In some embodiments, on a projection plane perpendicular to the normal direction of the indication surface 10 b , the projection of the antenna panel 20 is located within the projection range of the avoidance surface 10 d .

[0086] This helps to further reduce the distance between the area where the antenna panel 20 receives and transmits electromagnetic waves and the indication surface 10 b.

[0087] In some embodiments, on a projection surface perpendicular to the normal direction of the indication surface 10b, the projection area of ​​the indication surface 10b, the projection area of ​​the avoidance surface 10d, and the projection area of ​​the region where the antenna panel 20 transmits and receives electromagnetic waves decrease in sequence.

[0088] This helps to further reduce the distance between the area where the antenna panel 20 receives and transmits electromagnetic waves and the indication surface 10 b.

[0089] The specific number of the indication surfaces 10 b is not limited, and may be one or more, so as to meet the adaptation requirements of different numbers of antenna panels 20 .

[0090] The relative position relationship between the multiple indicating surfaces 10b is not limited. For example, there are two indicating surfaces 10b, and the two indicating surfaces 10b intersect each other; or, there are two indicating surfaces 10b, and the two indicating surfaces 10b are arranged in parallel on opposite sides of the housing 10.

[0091] In some embodiments, see Figure 5 and Figure 7 , the other parts of the housing 10 are all located on the same side of the indicating surface 10b along its normal direction.

[0092] That is, the other parts of the housing 10 do not extend from one side to the other side of the indication surface 10 b along the normal direction thereof.

[0093] In this way, during daily use, the aerosol generating device can use the indicator surface 10b as the contact surface when placed, so as to suppress the rolling and sliding movement tendency of the aerosol generating device, reduce the risk of the aerosol generating device falling, and help to maintain the stable placement of the aerosol generating device.

[0094] The specific arrangement position of the indication surface 10b on the housing 10 is not limited, and the indication surface 10b is located at one end of the housing 10 along one of its length direction, width direction and height direction. Figure 1 The indicating surface 10b is located at one end of the housing 10 along its length direction.

[0095] In the embodiment where the other parts of the housing 10 are located on the same side of the indicating surface 10b along the normal direction thereof, see Figure 5 and Figure 7 The indicating surface 10b extends to both ends of the shell 10 along the length direction of the shell 10, which is beneficial to increase the area of ​​the indicating surface 10b, thereby helping to improve the stability of the aerosol generating device during placement.

[0096] In some embodiments, see Figure 2 and Figure 3 The aerosol generating device further includes a power supply assembly 30, which is electrically connected to the antenna panel 20 and is at least partially located in the mounting cavity 10a.

[0097] The power supply assembly 30 is used to provide electric energy to the antenna panel 20, the heating device and other power-consuming devices in the aerosol generating device to enable them to operate normally.

[0098] In some embodiments, the outer surface of the power supply component 30 is provided with a mounting surface 30a, the mounting surface 30a is flat and faces the indicating surface 10b, the normal direction of the mounting surface 30a is parallel to the normal direction of the indicating surface 10b, and the antenna panel 20 is in contact with the mounting surface 30a.

[0099] In this way, on the one hand, it is convenient to directly identify the installation position of the antenna panel 20 during the assembly of the aerosol generating device, thereby improving the efficiency of assembly; on the other hand, the mounting surface 30a and the indicating surface 10b are parallel to each other, which facilitates the placement of the antenna panel 20 on the mounting surface 30a, and can directly achieve the purpose of the radiation direction of the antenna panel 20 facing the indicating surface 10b and being the same as the normal direction of the indicating surface 10b, thereby further improving the efficiency of the assembly operation.

[0100] It is understandable that the antenna panel 20 is fixed on the power assembly 30 so that the antenna panel 20 can enter or exit the installation cavity 10a along with the power assembly 30, and at the same time, it is also convenient to realize the electrical connection between the power assembly 30 and the antenna panel 20.

[0101] The specific structure of the power supply assembly 30 is not limited, for example, see Figure 4 The power supply assembly 30 includes a battery 31 and a mounting bracket 32. The mounting bracket 32 ​​is provided with a fixing groove, and the battery 31 is arranged in the fixing groove.

[0102] Understandably, see Figure 4 The mounting surface 30 a is disposed on the mounting bracket 32 ​​.

[0103] The specific method for fixing the antenna panel 20 and the power supply assembly 30 is not limited. For example, the antenna panel 20 and the power supply assembly 30 are fixed by bonding.

[0104] In some embodiments, see Figure 4 The outer surface of the power supply component 30 is provided with a mounting groove 30b, the mounting groove 30b is open to form an opening on the side facing the indication surface 10b, and the inner wall of the mounting groove 30b away from the opening forms a mounting surface 30a, and at least a part of the antenna panel 20 is located in the mounting groove 30b.

[0105] In this way, the position of the antenna panel 20 is constrained by the inner wall of the mounting groove 30b, which facilitates the fixation of the antenna panel 20. At the same time, it is convenient to reduce the gap between the power supply component 30 and the inner wall of the mounting cavity 10a, thereby improving the space utilization in the mounting cavity 10a and reducing the risk of the power supply component 30 shaking in the mounting cavity 10a and causing the electrical connection between the power supply component 30 and other devices to short-circuit.

[0106] It can be understood that the mounting groove 30b is located in the mounting cavity 10a.

[0107] Various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.

[0108] The above description is only the preferred technical solution in the embodiment of the utility model, and is not used to limit the protection scope of the embodiment of the utility model. For those skilled in the art, the embodiment of the utility model can have various changes and variations.
